The HardBoilder (ハードボイルダー Hādo Boirudā), designated the "MB1000RV", is Kamen Rider Double's personal Honda CBR1000RR motorcycle, based on the original SkullBoilder used by Kamen Rider Skull. Like Kamen Rider Double, the HardBoilder is black and green and is also able to change forms by swapping out the back half of the motorcycle after docking with the RevolGarry.
